With the scale of modern enterprises’ increase, it’s more difficult to manage the variety financial information which is produced during the construction and operation of a project. As a result, in modernized enterprises, the information management will play an more and more important role. Enterprise information management permeate a lot of respects of working for daily enterprise, no matter it is its function one’s own or given play to, are all the innovation of enterprises, development and economic benefits, have made remarkable contribution.But on the other hand, it brings about not only convenience and efficiency problems,but also great challenges in the field of data security and privacy protection. How to ensure the security of the financial information, protection of privacy and assurance of confidentiality has become more and more important for the vendors.Moreover because users usually have different roles and access privileges, date authenticity must be assured even when the data object that a user has access to consist of subset(s) of the signed data.Main function of this system is to realize systematization of financial administration, inquiry and management of the salary of the journal account systematized. At the same time, because XML as a platform-independent description language, is widely used because of it’s high-extensible mechanism. For the more complex financial information, we manage them using XML. But existing solutions such as Merkle hash technique lead to leakages of structural information, which can be used to infer sensitive information, which in turn would lead to privacy and confidentiality breaches. So we need authenticate subset of signed data objects without leaking. And we can compute only one signature per data objects.
